The species is highly variable, with certain of its widely dis- persed and somewhat isolated populations posing under different names; hence, the numerous synonyms. The populations which occur in the north central Pacific from Mid- way through Hawaii have been separately treated as T. venusta Dcshaves (Dall. Bartsch, and Rehder, 1938). individuals from this area are usuallv somewhat larger than typical T. pcma from the central por- tion of the range and often possess reddish radiations on the beak. Such characters, for example, are relatively rare in popu- lations from the Philippines, but in East Africa, indi\iduals with reddish umbonal rays and slightl}' blunt posterior rostrations have been called T. semilacvis von Martens. Other variations that have been named in- clude specimens with bright yellowish coloration, T. .s-ulphiirca Lamarck, those living in the Red Sea, T. pharaonis Hanley,.
